A series of snow storms combined with no thaws have led to a massive snowpack throughout the Tri-Lakes area. With that, comes the heightened risk of avalanches, according to a local avalanche expert. The Adirondack Daily Enterprise reports Josh Worth, a local avalanche expert, has taught avalanche safety and educational courses since 2006, and spent much of his life as a ski patroller and safety manager at Mammoth Mountain, a ski resort on the California side of the Sierra Nevada mountains.
